摘      要：Application of inorganic fertilizers improves crop yields but costs and adverse health effects often discourage their applications. This study therefore aims at evaluating the combined effects of cassava peel compost with poultry manure and mineral fertilizer on growth and yields of Corchorus olitorius. Pots （factorial laid out in a randomized complete block design） and field （split-plot with fertilizer being the main effect and the varieties the sub plot effect） experiments were carried out during rainy season at Ibadan, Nigeria. Treatments consisted of 0, 5, l0 and 20 t/ha composts prepared from cassava peel and poultry manure in ratio 3：1 and mineral fertilizer （NPK 15：15：15） at the rate of 250 kg/ha, using two varieties of C. olitorius. Five and six weeks after planting （WAP）, plants were assessed for growth and yields in pot and field experiments respectively, and also in residual studies. Application of compost significantly improved growth （heights） （36.50-41.56 cm）, while morphological and dry weight values increased with increase in compost. Marketable yield increase of 13.2%, 22.3%, 32.1% and 29.3% were recorded using 5, 10, 20 t/ha compost and NPK fertilizer respectively in the field. Corresponding increase when ratooned were 40.0%, 42.9%, 57.1% and 52.0%, respectively. Application of compost at the rate of 20 t/ha performed better in the main and residual effect experiments compared to NPK fertilizer and other compost rates. Application of cassavas peels compost at the rate of 20 t/ha proved to be adequate for optimum growth and yield performance of C. olitorius.
